Before Christianity there was an Anglo-Saxon goddess of spring named Eostre. Her companion was a hare. As Christianity spread they often included symbols and religious days of other religions to make it easier for people to convert.

Here is an interesting article to give you information -

"All the fun things about Easter are pagan. Bunnies are a leftover from the pagan festival of Eostre, a great northern goddess whose symbol was a rabbit or hare. Exchange of eggs is an ancient custom, celebrated by many cultures. Hot cross buns are very ancient too. In the Old Testament we see the Israelites baking sweet buns for an idol, and religious leaders trying to put a stop to it. The early church clergy also tried to put a stop to sacred cakes being baked at Easter. In the end, in the face of defiant cake-baking pagan women, they gave up and blessed the cake instead."
